To aZZ whom it may concern Be it known that ARTHUR HENRY LYMN,

spectively, residing at 40 Westminster Palace Gardens, Victoria street, London, S; England, Vanderbilt Concourse Building, 52 Vanderbiltavenue, New York, U. S. A., and d0 \Vestminster Palace Gardens, Victoria street, London, S. IV, England, have .invented new and useful Improvements in and Relating to Gas-Producers, of which the fpllowing is a specification. Y

Our invention relates to improvements in and relating to gas producers.

F or obtaining the: most economical results and the best gasifying effect the gaps formed in the mass of the fuel due to caking must be filled up and clinkering of the ash must be prevented. This is effected by moderate agitation of the charge, and by admitting continuously new layers into the various zones of reaction in the producer.

In order to attain an eiiicient agitation of the fuel, the producer may be provided with means which enable thewhole or part of the contents of the producer to be moved in a more or less horizontal as well as vertical direction; such movement of the producer contents causing agitation of the charge un der treatment and a breaking up of parts which have caked or clinkered together.

The devices used for thus agitating the whole area and cross section of the charge consisted of means for mechanically raising and lowering the whole or part of the revolving base in relation to the stationary part. In other devices the surface of the revolving grate comprises plates arranged side by form faces adapted to break up the clinker and convey the same toward the pan. In

some cases the helical surfaces are so eonstrncted that they gradually merge into a cyllndrlcal contour. In other constructions a conical grate is provided with spiral steps for pushing the ashes and incombustible matter towardits outer edge or periphery, curved ribs or vanes being provided at the outer termination of these stepsfor expelling the ashes.

In all these devices a great number of spaces is left between the projecting and cut-away portions of the surface which quickly fill up with hard setting clinker and ashes so that the device is bound to act after ashort time more or less as a cone thus failing not only to raise and lower the fuel but also to convey the ashes toward the shell of the producer.

Now the object of our invention is to obviate these disadvantages.

To eifectthe agitation of the lower part of the charge in a vertical as well as in a more or less horizontal direction a grate is rigidly mounted upon a revoluble ash bowl the whole or part of the under side of said grate adjacent to the producer contents is made of incomplete spiral, screw-propeller, whirl or similar configuration symmetrically arranged around a center, the surfaces of whichaccording to the'invention have a very gradual rise terminated by abrupt shoulders of considerable depth. To obtain such gradual lifting surfaces and at the same time to obtain a considerable drop, these surfaces and shoulders are necessarily few in number not exceeding four, and the shoulders are angularly widely separated.

In addition to such agitation in a vertical direct-ion as mentioned above, the grate or air distributer may be of such a shape that when same is revolved a further agitation of the charge takes place in a horizontal direction as well, preferably in such a direction as to cause crushing and disintegrating of the lower portion of the charge against the producer shell, and, simultaneously. a movement of the lowest portion ranged relatively to each other and to the axis of rotation of the grate in such way that the cylindrical surfaces of said semicylinders at the ends remote from the axis of rotation of the grate protrudelaterally toward the producer shell.

In order that the details of construction and action of-our invention may be more clearly' understood, reference is made to the accompanying drawings which show by way of example apparatus suitable for carrying out our invention.

In the accompanying drawings Figure 1 shows diagrammatically a sectional elevation of a gas producer with the agitating device;

Fig. 2 is a diagrammatic sectional-plan on a larger scale showing the device for causing a. crushing and disintegrating of the charge against the lower part of the shell.

Fig. 3 is an elevation of the device used for simultaneously raising or lowering part of or the whole area of the charge as well as producing the movement of the lower part of the charge in a horizontal direction;

Fig. 4 shows in sectional elevation a modification of said device actuated from the rotatable bowl, and also the grate and blast distributer; this latter section being taken along the line 7 z of Fig. 9..

Referring to the drawings a indicates the rcvoluble ash bowl, 6 is the producer shell or casing, 0 the top of the producer and g is the grate or blast distributor. I p

In order to effect the simultaneous raising or lowering of the whole charge, at regular or irregular intervals the uppersurface of the grate is constructed of one or more incomplete spirals or whirls; or the surface may be formed in one or more raised faces shaped like screw. propeller blades or wedges. It is however essential that the surfaces have a verygradual gradual riseterminated by abrupt shoulders of considerable depth. This can only be done by providing a a very limited number of projecting portions or shoulders not exceeding four.

The grate may also, be so. shaped that the rotation of the ash bowl causes the charge of the producer to move in a more or less horizontal plane. The accompanying drawlngs show by way of example shapes suitable for this purpose. the sides of the grate have the shape of two vertical half-cylinders laterally displaced along their dividing surfaces on the line (Fig. 2) which onrevolving in the direction of the arrow shown in Fig. 2, dis

place said charge in the horizontal direction toward the producer shell. In this way the crushing action on the ashes as mentioned aboveis effected. Fig. l shows the annular channels 1- and the tangential holes r for admitting blast to the charge. The blast is adm tted from, below t e grate at r and In Figs. 2 and 3 teac es partly leaves peripherally around the device for raising and lowering the charge from cure by Letters Patent of the United States is:

1. In a gas producer, a revoluble ash bowl and a grate fixed thereupon, said grate having upper surfaces of a substantially-interrupted spiral configuration, said surfaces having a very gradual rise terminated by abrupt shoulders of considerable depth and being widely separated angularly, thereby providing only a few upwardly directed projections.

2. In a gas producer a stationary shell and a revoluble ash bowl and a grate fixed thereupon, said grate having the shape of laterally displaced vertical sections of a cylinder and having upper surfaces of a substantially interrupted spiral configuration,

said surfaces having a very gradual rise, terminated by abrupt shoulders of considerable depth and being widely separated angularly, thereby providing only a few upwardly. directed projections.

3. In a gas producer a stationary shell, a revoluble ash bowl, a grate fixed thereupon and surfaces on the upper side of said grate of spiral configuration symmetrically arranged around a center andhaving a very gradual'ris'e terminated by abrupt shoulders of considerable depth and being Widely separated angularly thereby providing only a few upwardly directed projections.

4:. In a gas producer a stationary shell, :1 revoluble ash bowl, a grate fixed thereupon and surfaces on the whole of the up per side of said grate of spiral con'figura tion, symmetrically arranged around the axis of rotation of the grate and having a very gradual rise terminated by abrupt shoulders of considerable depth and being widely separated angularly thereby providing only a few upwardly directed projections.

5. In a gas producer a stationary shell, a revoluble ash bowl, a grate fixed thereupon, said grate consisting of vertical semicylinders eccentrically arranged relatively to each other and to the axis of rotation said shell.

6. In a gas producer a stationary shell, a revoluble ash bowl, a grate fixed thereupon, said grate consisting of vertical semicylinders eccentrically arranged relatively to each other and t0 the axis of rotation of the grate in such a way that their cylindrical surfaces at the ends remote from said axis of rotation protrude laterally toward said shell and surfaces on the upper side of widely separated angularly, thereby providing only a few upwardly directed pro- 15 jections.

In testimony-whereof we have signed our names to this specification in. the presence of two subscribing witnesses.
